LokoCar Rubber Fuel Hose Line 3/4 in ID SAE 30R7 25ft - Durable 300psi

In this review the LokoCar Rubber Fuel Hose Line is evaluated for mechanics, hobbyists and fleet technicians who need a robust, fuel-compatible replacement hose. The bottom line: this 25ft hose stands out because it pairs a 3/4 in ID and SAE 30R7 construction with a 300psi working pressure, making it a straightforward choice when durability and compatibility with diesel, gasoline and biodiesel matter. It feels engineered for workshop use rather than decorative or light-duty plumbing, and the review focuses on real-world fit, materials and handling.

Key Features

• 3/4 in ID and 1.06 in OD: the internal and external diameters give predictable flow and make it easy to match common fuel fittings without guessing.
• 25 ft length: provides ample run for most engine bays and equipment layouts, reducing the need for couplers or extra joints.
• 300psi working pressure: suitable for many fuel system and oil cooling applications where moderate pressure capacity is required.
• NBR and braided polyester construction: the nitrile rubber and braid resist oil and wear, so the hose handles hydrocarbons and abrasion in routine shop environments.
• Wide temperature range: rated from -40F to 257F, it remains flexible in cold starts and stable under higher under-hood temperatures.
• SAE 30R7 standard compliance: meeting this industry standard means predictable performance for fuel system and steam emission uses.

Who It's For

This hose is aimed at automotive technicians, diesel service shops and DIYers who need a reliable, oil-resistant fuel line for engines, oil coolers or similar applications. Its blend of NBR and braided polyester makes it well suited for vehicles, small equipment and stationary engines that use diesel, gasoline, biodiesel or oil-based lubricants.

It is not a specialized high-pressure injection line for modern direct-injection gasoline systems, nor is it intended as white plumbing or compressed-air hose. Buyers needing extremely high-temperature, chemical-specific or OEM-certified lines for injection rail pressures should look elsewhere.

Pros & Cons

Pros

• Durable construction resists oil and wear, extending service life in engine compartments.
• Compatible with a wide range of media including diesel, gasoline and biodiesel, reducing the need for multiple hose types.
• Solid working and burst pressure ratings (300psi working, 1200psi burst) that cover many common fuel and oil cooling tasks.
• Flexible across a broad temperature range, which helps during cold-weather starts and hot operating conditions.

Cons

• At 25 ft the length may be excessive for some installations and could require trimming or additional clamps.
• Not designed for very high-pressure fuel injection systems where OEM-specified hoses are required.

Our Verdict

The LokoCar 3/4 in ID rubber fuel hose is a practical, value-oriented choice for most fuel system and oil cooling needs because it combines SAE 30R7 construction, oil-resistant NBR material and a wide temperature range. Choose it if you need a dependable replacement hose for diesel, gasoline or biodiesel lines; opt for a specialized OEM high-pressure hose if your application involves fuel injection rail pressures.

Frequently Asked Questions

Can this hose carry gasoline and diesel?
Yes. The NBR material and SAE 30R7 design are compatible with gasoline, diesel, biodiesel, oil and grease.

Is the length fixed or can it be cut to size?
The hose comes as a 25 ft length and can be trimmed to fit; use proper clamps and fittings rated for the hose ID.

Will it handle under-hood temperatures?
Yes. The rated temperature range of -40F to 257F makes it suitable for typical under-hood heat and cold conditions.
